TABLE.

SPECIFICATION forming part of Letters Patent No. 256,849, dated April25, 1882.

Application filed October 31, 1881. (No model.)

To all whom it may concern:

Be it known that I, OLOF NILSSON, a citi zen of the United States,residing at Chicago, in the county of Cook and State ot'Illinois, haveinvented certain new and useful Improvements in Tables; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, of whichFigure 1 is a perspective view of an ordinary center table, showing inpart the tnechanism by which the top is adjustable to any desired angle;Fig. 2, a side View of the same, showing the top as inclined to an angleof fortyfive degrees; Fig. 3, acentral vertical section, showing themechanism by means of which the top is held in place when adjusted toany angle; and Fig. 4, across-section taken on the line 4 4, Fig. 2,showing a detail.

My invention relates to the class of tables of which the adjustable topsmay be inclined to any desired angle; and it consists in adjusting thesaid tops by means of a mechanism for this purpose.

In the drawings, A is a table-top, resting upon the upper end of thepedestal B.

C and C- are supports to afford a broader surface than is ofl'ered bythe mere end of the pedestal, upon which to rest the top when in ahorizontal position, the support C at the same time offering a place onwhich to attach the table-top by means of hinges c, inserted therein andin the under side of the tabletop A. These supports project from threesides of the pedestal B, each one being dovetailed into the side fromwhich it extends,and braced by supports a a, to afford greaterresistance in case any weight or pressure is brought to bear upon saidtop away from its center when in a horizontal position. The fourth sideof the shank is unprovided with a support of the kind just mentioned;but instead a different mechanism is employed, which operates to supportthe said fourth side of the top, since that also requires support whenthe table-top is used in a horizontal position, and at the same timeembodies a principal part of my invention, for which reason it willrequire particular explanation. This mechanism consists of the jointedsupport D D, the part D being hinged at one end to the under side'of thetable-top, as shown att, and joined to the part I) at its other end,also by means of a hinge, s, forming a hinged joint. This is similar inappearance to the support a a; but in addition to merely supporting thetop when in ahorizontal position it is the means, when assisted by otherfeatures of the mechanism hereinafter described, by which the top A isfirmly held in place when inclined to any angle; and it consists,further, in the use of a screw, E, passed through the part D into aslot, 1', cut verticallyalong the face of the pedestal B. The rear partof this slot 1' is made wider than the front to produce SlJOlildeI'S,against which a sliding bar, q, (also wider than the front part of thesaid slot, and introduced through a hole made for the purposein the topofthe pedestah) may be pressed by the tightening t f the screw E into ahole, forming a female screw,p, toward the lower end of the said slidingbar, in order firmly to hold the top A in place when inclined byexerting both an inward pressure of the part D against the face of thepedestal and an outward pressure of the sliding bar against theshoulders in the slot. This sliding bar q, when relieved from itspressure. against the shoulders formed in the slot 1' by the looseningofthe screw E, is free to move vertically up and down with the movementsof the tableto I have confined the description of my invention to itsapplication in tables, as it is in this connection that the mechanismwill be mostly employed for purposes of writing, reading, displayingengravings, &c.; but it is obvious that it is equally as adaptable tomany other articles for like purposes-writing-desks or book-rests to fitupon the lap, or to be used while the writer or reader, as the case maybe, occupies an inclined position, for instance.

What I claim as new, and desire to secure by Letters Patent, is-- Thecombination of the pedestal B, having a slot, 1', expanded toward itsinner end, bar q within the expanded portion of the slot, and adapted toslide up and down therein, tabletop A, hinged to the pedestal B on thesame side as the slot. 1', jointed support D D, hinged to the under sideof the table-top on the same side as the slot 1', and set-screw E,passing through the lower end of said support and also into the slot 1'and through the sliding bar q, whereby the table-top may be adjusted toany angle and firmly secured there, substantially as described.

OLOF NILSSON. In presence of-- C. G. LINTHIGUM, WM. H. DYRENFORTH.
